NAME ^

POE::Component::Server::IRC::Common - provides a set of common functions for the POE::Component::Server::IRC suite.

SYNOPSIS ^

  use strict;
  use warnings;

  use POE::Component::Server::IRC::Common qw( :ALL );

  my $nickname = '^Lame|BOT[moo]';

  my $uppercase_nick = u_irc( $nickname );
  my $lowercase_nick = l_irc( $nickname );

  my $mode_line = 'ov+b-i Bob sue stalin*!*@*';
  my $hashref = parse_mode_line( $mode_line );

  my $banmask = 'stalin*';
  $full_banmask = parse_ban_mask( $banmask );

  if ( matches_mask( $full_banmask, 'stalin!joe@kremlin.ru' ) ) {
        print "EEK!";
  }

  my $results_hashref = matches_mask_array( \@masks, \@items_to_match_against );

  my $mode_change = gen_mode_change( 'abcde', 'befmZ' );

  my $passwd = mkpasswd( 'moocow' );

DESCRIPTION ^

POE::Component::IRC::Common provides a set of common functions for the POE::Component::Server::IRC suite. There are included functions for uppercase and lowercase nicknames/channelnames and for parsing mode lines and ban masks.

FUNCTIONS ^

u_irc

Takes one mandatory parameter, a string to convert to IRC uppercase, and one optional parameter, the casemapping of the ircd ( which can be 'rfc1459', 'strict-rfc1459' or 'ascii'. Default is 'rfc1459' ). Returns the IRC uppercase equivalent of the passed string.

l_irc

Takes one mandatory parameter, a string to convert to IRC lowercase, and one optional parameter, the casemapping of the ircd ( which can be 'rfc1459', 'strict-rfc1459' or 'ascii'. Default is 'rfc1459' ). Returns the IRC lowercase equivalent of the passed string.

parse_mode_line

Takes a list representing an IRC mode line. Returns a hashref. If the modeline couldn't be parsed the hashref will be empty. On success the following keys will be available in the hashref:

   'modes', an arrayref of normalised modes;
   'args', an arrayref of applicable arguments to the modes;

Example:

   my $hashref = parse_mode_line( 'ov+b-i', 'Bob', 'sue', 'stalin*!*@*' );

   $hashref will be 
   {
        'modes' => [ '+o', '+v', '+b', '-i' ],
        'args'  => [ 'Bob', 'sue', 'stalin*!*@*' ],
   };
parse_ban_mask

Takes one parameter, a string representing an IRC ban mask. Returns a normalised full banmask.

Example:

   $fullbanmask = parse_ban_mask( 'stalin*' );

   $fullbanmask will be 'stalin*!*@*';
matches_mask

Takes two parameters, a string representing an IRC mask ( it'll be processed with parse_ban_mask() to ensure that it is normalised ) and something to match against the IRC mask, such as a nick!user@hostname string. Returns 1 if they match, 0 otherwise. Returns undef if parameters are missing. Optionally, one may pass the casemapping ( see u_irc() ), as this function ises u_irc() internally.

matches_mask_array

Takes two array references, the first being a list of strings representing IRC mask, the second a list of somethings to test against the masks. Returns an empty hashref if there are no matches. Matches are returned are arrayrefs keyed on the mask that they matched.

gen_mode_change

Takes two arguments, being a strings representing a set of IRC user modes before and after a change. Returns a string representing what changed.

  my $mode_change = gen_mode_change( 'abcde', 'befmZ' );
  $mode_change is now '-acd+fmZ'
unparse_mode_line

Takes one argument a string representing a number of mode changes. Returns a condensed version of the changes.

  my $mode_line = unparse_mode_line('+o+o+o-v+v');
  $mode_line is now '+ooo-v+v'
validate_chan_name

Takes one argument a channel name to validate. Returns true or false if the channel name is valid or not.

validate_nick_name

Takes one argument a nickname to validate. Returns true or false if the nickname is valid or not.

parse_user

Takes one parameter, a string representing a user in the form nick!user@hostname. In a scalar context it returns just the nickname. In a list context it returns a list consisting of the nick, user and hostname, respectively.

mkpasswd

Takes one mandatory argument a plain string to 'encrypt'. If no further options are specified it uses crypt to generate the password. Specifying 'md5' option uses Crypt::PasswdMD5's unix_md5_crypt function to generate the password. Specifying 'apache' uses Crypt::PasswdMD5's apache_md5_crypt function to generate the password.

  my $passwd = mkpasswd( 'moocow' ); # vanilla crypt()

  my $passwd = mkpasswd( 'moocow', md5 => 1 ) # unix_md5_crypt()

  my $passwd = mkpasswd( 'moocow', apache => 1 ) # apache_md5_crypt()
chkpasswd

Takes two mandatory arguments, a password string and something to check that password against. The function first tries md5 comparisons ( UNIX and Apache ), then crypt and finally plain-text password check.
